Step 1: Prepare the Cranberry MixtureIn a small saucepan, combine 1 cup of water and the cranberries. Bring to a simmer over medium heat, stirring occasionally until the cranberries burst (about 5–7 minutes). Once done, let the mixture cool for a few minutes.
Step 2: Infuse the RosemaryWhile the cranberry mixture is cooling, bring another 1 cup of water to a simmer in a separate pot. Add the rosemary sprigs and simmer for 5 minutes to allow the rosemary to release its flavor. Remove from heat and discard the rosemary sprigs.
Step 3: Blend CranberriesUsing a blender or food processor, blend the cranberries and their cooking water until smooth. If you prefer a clearer drink, strain the cranberry mixture through a fine sieve or cheesecloth, pressing gently to extract as much juice as possible. Set aside.
Step 4: Mix LemonadeIn a large pitcher, combine the remaining 2 cups of water, fresh lemon juice, cranberry mixture, rosemary-infused water, and honey (or your preferred sweetener). Stir well to combine.
Step 5: Adjust to TasteTaste your lemonade and adjust as needed. For more sweetness, add extra honey or maple syrup. For a stronger lemon flavor, squeeze in more lemon juice.
Step 6: Serve and GarnishPour over ice and garnish each glass with fresh cranberries, a sprig of rosemary, and lemon slices for a beautiful presentation. Enjoy!
